Answer:
The correct option is B. II and III only
Step-by-step explanation:
kinetic can be transformed to potential energy and potential energy can be transformed to potential energy.
potential energy of the body is the stored energy of of an body.
for example if a spring at rest in given some initial velocity to compress the spring when the spring comes to momentary rest the kinetic energy given to the spring is concerted to potential energy which is stored in the spring
and when it comes back to its original position the potential energy of the spring is converted to kinetic energy
